Title (EN) COMPRESSOR FOR INJECTION COMPRESSION MOLDING MACHINES
(FR) COMPRESSEUR POUR MACHINES DE MOULAGE A INJECTION PAR COMPRESSION
Abstract:
(EN) The present invention provides a compressor for an injection compression molding machine, which has control characteristics superior to these of a hydraulic compressor, and which is therefore capable of molding a material with a higher accuracy and better reproducibility. A compressing pin (32) is fixed to the tip portion of a ball screw (29) engaged with a ball nut (24) connected to a servomotor (19), which is provided on a movable platen (3), via a power transmission (35). In conjunction with the rotation of the servomotor, the compressing pin is moved axially with the ball screw to project from the movable platen toward a metal mold (100) and compress a molten resin packed in the metal mold.
(FR) Compresseur présentant des caractéristiques de réglage supérieures à celles d'un compresseur hydraulique, et permettant de mouler un matériau avec une grande précision et une meilleure reproductibilité. Un ergot compresseur (32) est fixé sur la pointe d'une vis à rotule (29) engagée dans un écrou à rotule (24) relié à un servomoteur (19), monté sur un plateau mobile (3), via une transmission de puissance (35). En combinaison avec la rotation du servomoteur, l'ergot compresseur se déplace axialement avec la vis à rotule pour faire saillie sur le plateau mobile en direction d'un moule métallique (100) et comprimer une résine en fusion contenue dans le module métallique.
